Wow. I used to have engineers at my old company who had similar defensive attitudes when people asked sincere questions. Always found it a bit odd because I enjoy explaining concepts and thrashing out details with others. Anyhow... No, I have not built one. I have built two. I'm aware of the limitations of IR tx/rx pairs when it comes to filament detection which is what led me here in the firstby looxonline - Tech-Talk

What was the reliability like with movement detection. I notice that you are looking for even just a single value difference between the two averages. It seems like ADC noise alone may be able to generate that. I am struggling to understand how movement of the filament would produce a different value across the ADC when the filament tolerance is around 0.005mm diameter these days. Surely any diffby looxonline - Tech-Talk

Did you ever have any issues with filament dust messing with the ADC readings and causing false triggers?by looxonline - Tech-Talk
